We assessed the effects of rotenone on aquatic invertebrate communities by comparing four prairie wetlands treated with rotenone to four control sites. Data collected one week before and three weeks… (More)

We evaluated effects of fish removal from a large, shallow lake that historically was an important feeding area for migrating diving ducks. In the decade before fish removal, turbidity was high,… (More)
